fix(eve): Slack follow-ups for legacy scheduled threads

[AndrewBarba]

What changed

• Wrap eve's internal Workflow resumeHook so cross-deployment resumes can wake legacy deployments that still consume the old eve workflow queue namespace.
• Add a legacy namespace constant and unit coverage for the migration behavior.
• Add a patch changeset for the published eve package.

Why

Scheduled Slack threads created before the agent-scoped Workflow queue change could still have active hooks owned by older deployments. After a newer deployment handled a Slack mention, Workflow could find the hook and record hook_received, but enqueue the wake-up on the new per-agent namespace. The old deployment did not consume that queue, so the Slack webhook appeared accepted and showed typing, but the parked session never resumed.

Impact

Follow-up mentions in scheduled Slack threads created by pre-namespace-change deployments can resume again after upgrading. New deployments that already respond on the current namespace are left unchanged.

Validation

• pnpm --filter eve exec vitest run --config vitest.unit.config.ts src/internal/workflow/runtime.test.ts src/internal/workflow/queue-namespace.test.ts src/execution/workflow-runtime.test.ts
• pnpm --filter eve typecheck
• pnpm --filter eve exec oxlint src/internal/workflow/runtime.ts src/internal/workflow/runtime.test.ts src/internal/workflow/queue-namespace.ts
